3-40 Mr. G. C. Champion on the 
in 1893. A slender insect, not unlike an Asclera (fam. 
(Hdemerid), green or bluish green, with the palpi, an- 
tenn, and sometimes the tibiz and apex of the abdomen 
also, testaceous or flavous ; the antennz very slender; the 
head small. Two males have been dissected. J. flavicollis 
appears to have been unknown to Pic. 
14. Idgia flavirostris. 
Idyia flavirostris, Pase. Journ. Ent. i. p. 43 (April 1860) ; Fairm. Ann. 
Soc. Ent. Fr. (6) ix. p. 44 (1889). 
g. Eyes small, distant, as in 2; anterior tarsal joints 1-3 
with a comb along their inner edge. Genital armature 
(PI. XI. fig. 14): lateral lobes long, narrowed outwards, their 
apices truncate and hooked beneath; median lobe gradually 
narrowed, curved upward at the tip. 
Hab. Cuina (Mus. Brit.), Chusan Is. (J. J. Walker), 
Ta-maon Isl., Hong Kong (Mus. Brit.). 
Of the eighteen examples of this species before me, in- 
cluding the type, one only, from the Chusan Is., is of the 
male sex. A close ally of J. flavicollis, with a longer pro- 
thorax and very elongate elytra, the anterior portion of 
the head, palpi, basal joints of the antennz, prothorax, and 
femora testaceous. The head is small and comparatively 
short. The tarsal claws are distinctly widened to about the 
middle. An allied form from China has been described by 
Fairmaire under the name J. moupinensis. 
15. Idgia virescens, sp. 0. 
@. Very elongate, narrow, subopaque, finely cinereo- 
pubescent, and sparsely nigro-setose ; obscure metallic green, 
the anterior half of the head, palpi, antennze, underside of 
prothorax, abdomen, coxe, femora, and tibiz in part, testa- 
ceous. Head scabroso-punctate, small, slightly produced in 
front, excavate between the eyes, the labrum transverse ; 
eyes distant; apical joint of maxillary palpi elongate; 
antennz very slender, long, joints 3 and 4 equal in length, 
those following still more elongate. Prothorax longer than 
broad, wider than the head, somewhat dilated at the middle, 
opaque, densely, very finely scabroso-punctate. Elytra very 
elongate, much broader than the prothorax, rounded at the 
tip; densely, rugulosely punctate, each with five series of 
conspicuous granules on the disc, the margins crenulate. 
Legs very long and slender; tarsal claws widened to about 
the middle. 
Length (excl. head) 84, breadth 2 mm.
